The study was made on reservoirs of infections (rodent, sheep, goat, dromedary), vectors (louse) and human-receptors. Examinations were made on smears examined with staining and indirect-fluorescente techniques and on sera examined by complement fixation test. Chlamydia psittaci appears very often in rodent, sheep, goat, dromedary and man. Antibodies against Coxiella burneti were found present in sheep, goat but mainly in dromedary and less than 16 years old boys.
